Description
Easily connect this external battery pack to an existing APC Smart-UPS X to instantly increase the amount of battery runtime to connected devices during a power outage. Please refer to your APC Smart-UPS X manual to confirm compatibility with this external battery back. The battery pack offers easy plug-and-play installation onto an operating APC Smart-UPS, ensuring power availability while runtime capacity is added. Through the APC Smart-UPS’ intelligent battery management and precision charging, the battery pack maintains the UPS system’s performance, reliability, and useful life. The APC battery pack provides scalable runtime to the APC Smart-UPS X, allowing multiple battery packs to be quickly added if the need arises. The battery pack operates equally in tower configuration, standing next to an APC Smart-UPS, or in rack-mount configuration, mounted below the UPS. Package Includes APC SMX120BP External Battery Pack, installation guide, and rack-mounting brackets.Specifications
